18/3.] FROM CELEBES AND THE PHILIPPINE ISLANDS. 1/1 



Hologerrhum philippintjm, Gthr. (Plate XVIII. fig. B.) 



This snake must be extremely scarce or very locally distributed, 

 as none of the collections from the Philippines which have reached 

 Europe during the last fifteen years contained another specimen. 

 However, there appears to be one example in the Paris Museum, 

 which has been figured by Jan under the name of Cyclochorus ma- 

 culatus (Iconogr. livr. xxxvi. 18/0, pi. 6. fig. 3). He states (Index 

 des Planches) that this specimen is from Java, which is very doubtful. 

 The groove of the posterior maxillary teeth is, in our specimen, not 

 lateral, as figured by Jan, but anterior. I should now describe the 

 nasal plate as divided rather than as single. Ventrals 144, sub- 

 caudals 40. 



POLYPEDATES S1MILIS. 



Closely allied to P. signatus, but entirely smooth. 



Canthus rostralis distinct ; loreal region concave, vertical ; eye 

 large ; tympanum not quite the size of the eye. Back and sides 

 smooth, without granulation. Fingers slender, quite free, with very 

 small disks ; toes slender, two thirds webbed, also with the disks 

 very small. Two small metatarsal tubercles. Inner nostrils narrow, 

 but wider than the Eustachian tubes ; vomerine teeth in two very 

 short oblique converging series between the inner nostrils. Upper 

 parts black, a well-defined greenish-white band runs along the upper 

 margin of the snout and eyelid, and along each side of the back. 

 No brown spots on the back or sides ; a whitish line along the coc- 

 cyx ; a well-defined whitish band along the margin of the upper lip, 

 terminating below the tympanum. Legs transversely barred with 

 brown and reddish white. Lower parts whitish.

Platvmantis MEYERI. 



Similar in habit to PL plicifera, but with more slender limbs. 

 Snout scarcely longer than the eye. Vomerine teeth on two very 

 short and very prominent oblique ridges, situated inwards and back- 

 wards of the inner nostrils, very far apart. Inner nostrils and Eus- 

 tachian openings narrow. Tympanum not half the size of the eye. 

 Back with rather short longitudinal folds. Disks of fingers and toes 

 extremely small. First finger a little longer than the second. Toes 

 with a rudiment of a web. Two small metatarsal tubercles. Brown- 

 ish above, marbled with darker ; a broad light reddish band from 

 the snout along the median line of the back. Lower parts whitish, 

 throat marbled with brown.
